Tuning your amp(s) is crucial to proper output and a long healthy life from your amplifier. By following the tuning steps below, your amp will produce maximum CLEAN power, provide the proper frequencies to your speakers / subwoofer(s) and provide many years of great audio!

Before starting the tuning process, you must complete the following steps:

• Power Wire (Proper size / Gauge) is connected from battery to TXD10005. ALL Fuses/Connections are installed and tightened per installation instructions.
• Ground Wire(s) (Proper Size / Gauge) is connected and tightened correctly.
• Plug and Play wiring harness is installed per installation instructions – for your model Toyota.
• Ensure that your OUTPUT plugs are NOT connected as shown in the installation diagram.

At this point your TXD10005 is powering on and you are ready to proceed to the tuning process.

Step 4: Remote turn on wire

Connect the Blue or Red remote turn on wire included in your PNP wiring system. NOTE: If using an aftermarket head unit, use the blue remote wire from your aftermarket head unit. See our Aftermarket installation instructions here:

Step 5: Subwoofer wire connection

Connect a short piece of 12G wire to your subwoofer output. Strip the ends and be sure the + and – do not come in contact with each other.

Step 6: Output Wire Connections

DO NOT PLUG IN THE BLACK MOLEX PLUGS FROM YOUR PLUG AND PLAY HARNESS AT THIS TIME! We will plug them in AFTER the tuning process has been completed.

Locate the Black Molex connectors that have the SHORT white / gray & purple/ green wires. They are located in the same bag with the Molex / RCA connectors.

NOTE: If you are using aftermarket head unit, you will want to refer our after market head unit / tuning video.

Step 7: Tuning Video Instructions:

NOTE: The TXD10005 is best suited to work with 4 Ohm Front & Rear Speakers. If you have upgraded your speakers, please be certain you are using a component set for your front speakers to ensure you are providing a 4 Ohm load. Resistance below 4 ohms may cause excessive noise.
